HENRY THURLOW', OF SKANEATELES, NEW' YORK.

MACHINE FOR THE TREATMENT OF LEATHER.

SPECIFICATION forming part of Letters Patent No. 386,667, dated July24,1888.

(No model.)

To all whom it may concern:

Be it known that l, HENRY THURLOW, of Skaneateles, in the county ofOnondaga and State of New York, havein vented an Improvement in Machinesfor the Treatment ofLeather, of which the following description, inconnec tion with the accompanying drawings, is a specification, likeletters on the drawings representing like parts.

This invention has for its object to provide a novel machine fortreating leather of various qualities, so as to give to its surface aproper and desirable finish.

My improved leather-finishing machine consists, essentially, as hereinshown, of a rotating cylinder provided with a series of dresser bars orslats, which, preferably, will be piv oted, with relation to the headsof the cyliir der, so as to be reversed and present either of the twofaces of the bars or slats outermost, one side or face of the said barsor slats being provided with teasels and the other side or face of thesaid bars or slats with a wire-card surface or equivalent abradingmaterial.

My invention consists, essentially, in the combination, with a frame andin a machine for the treatment of leather, of a reversible se ries ofdresser bars or slats provided with teasels, a locking device for saidbars or slats, and Wllll a support for the leather to be acted upon.

Other features of my invention will be pointed out in the claims at theend of this specification.

Figure 1 is a left-hand end elevation, partially broken out, of aiinishingmachine embodying my invention. Fig. 2 is a front cle vation ofmy improved machine, the same showing at the left one row of teascls,the gearing for automatically rotating the dresser bars or slats,partially shown in Fig. 1, being entirely omitted. Fig. 3 is a sideelevation of one of the dresser bars or slats removed, it being brokenout in the direction of its length to save space upon the drawings; Fig.4, an edge elevation of Fig. Fig. 5 is a section of Fig. 3 in the line00 ft, and Figs. 6 and 7 are details to be referred to.

A represents the standards of a frame of suitable shape to support theworking parts, together with the shaft a, having mounted upon it nearits opposite ends the disks a a which latter are provided, as hereinshown, at

suitable intervals upon their peripheries with bearingblocks, as a, forthe reception of the short journals or arbors a a of the faces a a ofthe dresser bars or slats to be described. Each dresser bar or slat iscomposed of a side piece, I), bent at its ends to form end pieces, 1/If, and secured to the heads a a and the bottom bars, I) I), secured tothe end pieces, b If, there being left between the said bottom bars orslats an opening of suflicient size and suitable shape to receive thestems b of the teaselsa. Each dresser baror slat also,preferably, has,as a part of it, a back piece, c,which is covered with card-cloth, as ata. The dresser bars or slats, as described, have, it will be seen, twoworkingi'aces, one covered with teasels and the other with \vire'cl0th,and in practice the wire-cloth may be used to abrade or roughen theflesh side of the hide to raise the fiber, and thereafter the teaselssurface may be made to act upon the surface of the flesh side of theleather to give to it a finer finish than can be given to it by thewirecloth, fine finish being especially desirable in connection withcalf, sheep, goat, morocco, and kid leather; or the teasels may be usedto roughen and finish, and the cards act simply as a comb. The teaselsare firmly clamped between the side pieces, I), and bars I) b.

To confine the card to the back part, a, I prefer to provide the headsaialwith loops or flanges, as shown at a, Fig. at. Each head a is hereinshown as made longer than the head a and is provided near its oppositeends with holes, as b (see Fig. 6,) for the reception of a stud or pin,as b attached to a spring, as b", properly secured to the inner side ofone of the heads, as a, of the cylinder, the said stud or pin when usedconstituting a locking device by which to retain the dresser bar or slatin position with either of its two faces outwardly in operativeposition. These dresser bars or slats may be reversed whenever desired,so as to present their teasel-faces or their card-cloth faces, asdesired, orso as to present the teasel-l'aces and the cardcloth facesalternately.

In practice I prefer to provide each of the journals a, as shownpartially in Fig. 1, with a small pinion, f, and the said pinions willbe engaged by a large gear, 9, (partially shown in Fig. 1,) but mountedloosely upon the shaft 11, the partial rotation of the gear gautomatically effecting at the same time the reversal of the dresserbars or slats.

The leather to be acted upon by the finishing-machine hereindescribedwill besupported upon a suitable bed or apron, (1, herein shown underthe control of a foot-treadle, d", and a cord, d extended over a pulley,dfi

In practice I do not desire to limit my invention to the exact form ofbed or apron, as, instead, I may use any other usual or suitable supportcommonly employed in connection with leather finishing machines.

The shafta is shown as provided with usual fast and loose pulleys, bywhich, through a belt, the cylinder carrying the dresser barsor slatsmay be revolved at any desired speed.

In practice the locking device composed of the spring-actuated stud willbe omitted when the dresser bars or slats are to be-revolved or turnedsimultaneously through the pinions f and gear 9.

I prefer to secure the dresser bars or slats to disks mounted on ashaft, so as to form a cylinder, as shown; but I do not desire to limitmyself to this particular form of frame, as the said dresser bars orslats may be attached to and be supported by a vertical or horizontalreciprocating frame.

I claim 1. In a machine for finishing leather, a revolving cylinderhaving a series of reversible dresser bars or slats to hold teasels, andalocking device for said bars or slats, combined with a bed or apron tosupport the leather to be acted upon by the said teasels, substantiallyas described.

2". In a machine for finishing leather, a retating cylinder providedwith a series of pivoted dresser bars or slats, having one face providedwith teasels and one with Wire-cloth, the

combinatiomwith asupporting-frame, of areversible dresser bar or slatcontaining teasels, and a locking device to secure the said dresser barsor slats, substantially as described.

5. In a machine for finishing leather, a supporting-frame and aseries ofreversible dresser bars or slats containing teasels and wire cards andpivoted to said frame, combined with a locking device to secure thedresser bars "or slats, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two sub scribing witnesses.

HENRY THUR'LO-WV.
